Specicaton of Letters Patent.

To all whom t may concern.'

Be it known that I, WILLIAM A. BooK, a citizen of the-United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certainnew and useful Improvement in Car-Movers, of whichthe following is a full, clear, concise, and eXact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in car movers.

One object of the invention is to provide a device for moving cars along the tracks as for instance in freight yards and on sidings, which device comprises few parts relatively inexpensive to manufacture and easy of operation. y Y

Another object of the invention is to provide a car mover which willbe adjustable to various sizes of rails.

-A still further object of the invention ris to provide a car mover of the character above indicated which will in no wise injure or mutilate either the rails or car wheels against which it is placed during the operation of moving the car.

In the drawing forming a part of this specification, Figure 1 is a broken elevational view of a portion of a 'car wheel, a portion of a rail, and my improved car mover shown in position ready to move the car. lFig. 2 is a top plan view of the car mover shown in place on a rail. F ig. 3 is aa vertical, sectional view taken substantially on the line 3--3 of Fig. 2 and illustrating details of construction of the car mover. And Fig. 4 is a detailed sectional view taken substantially on the line 4 4 of Fig. 1 and illustrating details of construction.

In said drawing, the rail is indicated by the letter A, the same having a tread of usual form designated by the numeral 10. A portion of one of the wheels of a car is indicated by the numeral 11.

The improved car mover as shown, consists broadly of an operating lever designated generally by the letter B, a clamp designated generally by the letter C and a wheel engaging shoe designated generally by the letter D.'

The clamp C consists of two preferably like parts designated C-C, the same being loosely mounted on a pin 12 passing through suitable perforations in the top parts of the clamp elements C. The pin l2 is headed at each end as indicated at 13 so as to hold the parts in assembled relaion. Each of the clamp elements C is provided with a perforation 14 to accom modate the pin 12, the perforations 14 being slightly larger than the pin 12 so as to permit a certain amount of swinging movement of the clamping elements C with respect to the pin 12. rIhe opposed adjacent faces of the clamping elements C at the tops thereof in proximity to the pin 12 are somewhat beveled, as indicated at 15 so as to permit the relative swinging movement hereinbefore mentioned. At the bottoms, the clamping elements C are provided with depending flanges or fingers 16-16 adapted to engage the side edges of the tread 10 of the rail, the clamping elements C being formed as indicated at L11-1T to also fit on the top of the tread 10. Each clamping element C is also cut away below the pin 12 as indicated at 18 to permit relative movement therebetween as will be understood. The lever B may be made of any suitable form, preferably as a forging, and has a widened or enlarged section intermediate its ends as indicated at 19. This widened section contains a centrally disposed elongated opening 20 of sufiicient width to loosely accommodate the clamp C therein. The upper and lower walls of the opening 2O are curved as indicated at 21 to facilitate relative swinging movements between the lever B and the clamp C. The lower wall 21 also supports the clamp in a substantially vertical position when the device is being shifted along the track. rIhe side walls of the opening 2O are also y"flared downwardly so as to cooperate with the correspondingly inclined surfaces 20A of the clamp elements C- when the latter are wedged tight against the rail.

On the upper face of the enlarged section 19 ofthe lever B, bearing surfaces 9,222 are provided for the rounded headed ends 13 of the pin 12 so that said pin and the clamp carried thereby may move back and forth relatively to the lever B. The latter is provided however with upstanding shoulders 23 to limit the movement of the clamp and pin 12 toward the lower end of the lever B, as clearly indicated by Figs:

fork is received a depending flange 25'rofi the shoe D. On the upper faces of the arms of the forlrfrounded bearings are prof videdsas indicated at 26 to accommodate corresponding curved pivot lugs27, formed integrallywith the shoeD on opposite sides offthefiange25 so that,- aswill. beevide'nt,4| the'fshoe D is 'adapted for pivotal movement with respect to the lower `end-ofthe lever- BQ The-eXtreme end of the lever B1 is' bevL eled or'chamfered las indicated at,A 28j toY permit ther-pivotal movements of the shoe D',"it' being -'understo`od that the latter'is 'of a "width* at *its c topzcorresponding substantially to the width of th'elever'Bfat its lowerend. The bearing `surface 29 ofthe shoe DY is curved PtoV conform to theA 'curvar ture offtheirims of car wheelsnow'in service. To Vpreventl accidental separation ofA tl1eshoe^^D"`andfthe Ilever B, any suitable means maybe employed such` as' the pinrBO which passes throi1ghan`-arciiate slot 31 in the flangez25 andhas'fits ends seated inthe forked end of Vthe lever yB.

Tof obtainthe necessary leverage in 'operating thelever B, lthe latter may'have an extended integral arm, but preferably'I "em=l ploy a handlefas indicated at .32 whichvk is slipped over a'ftangS formed on'the `lever B." Said-handleV 32 may well be a hollow pi Je' or a` wooden stock;

he `operation'is. as follows. The operi atorfappliesv the" clamp 'C in'its loose con;

ditionfto the tread' 10 of the railV adjacent therwheel "of thezcar to be moved and with the shoe'D inengagement withV therim of y the wheel;l Pressure is then exerted on the lever Bi i byl` forcing the outer J end thereof downwardly' and as'this movementoccurs, iti is evidentthat the lever B sliding down Y the clamping .element C will wedge' the latte'rand thereby'cause the clamp'torseoure'ly grip the rail and prevent slipping thereof. The vclampV thereafter acts as a fulcrumand the Vlower endofthe Vleverr is elevated so as to Ilift'the shoe D which in turn causes the wheel vto rotate and advance the carin a well-known manner. To advance the car mover another step4 forwardly to move the car still" farther, the operator lifts the lever B"which will loosen theclamping elements Cfso that'the clampl can beshifted` along the tread ofthe rail and the operation repeated as desired.v

With my construction, as will be ap]- parent from the foregoing description, I am enabled to obtain a grip on rails Ahaving treads of diderent sizes and at the same time to avoid any injury to the rail which has heretofore been a disadvantage in connection witht thefuse of other'typesH of? car movers commonly employed andl whic-hhavc necessitated using sharp teeth or projections to biteinto thetread of the rail in order to obtain the necessary fulcrum in actuating the lever. My improved car mover may beV manufactured at comparatively small expense, ycomprises few parts, is of simple construction throughout and easily operable.

Although Iihave'nherein shown and described what I now consider to be the preferred manner ofcarryinggout theiinventiongthefsame is vmerely illustrative 'and contemplate `'all a changesv fand modifications Y asl comeA withiir'the `scope of the claims ap-l pende'd'hereto!` Y Y I claim-:f

In Witness that I claim the foregoing I have hereunto subscribed my name this 30th day of Aug., 1919.
